在铁路货运工作中,用敞车、平车运输散装货物时,如:煤、矿石、砂、石灰等,由于列车高速行驶及风的吹刮,不仅沿途散失很大,而且由于粉尘随风飘散,污染沿线建筑设施,危及附近居民身体健康。据此,苏联新西伯利亚铁路运输工程学院用纤维纸和石油加工工业的残渣研制成一种可形成薄膜的混合物,这种混合物在散装货物表面喷射后即能形成薄膜,可以抗击列 In the railway freight transportation, when using gondola cars and flat cars to transport bulk cargoes, such as coal, ore, sand, lime and the like, the high-speed trains and the blowing of the wind not only lose a lot along the way, but also drift out of the wind due to the dust, Pollution of building facilities along the line endanger the health of nearby residents. Accordingly, the Soviet Union Novosibirsk Railway Transport Engineering Institute with fiber paper and petroleum processing industry residue developed into a film can be a mixture of such mixture in the bulk cargo surface spray to form a film that can fight column
